Water output device and control method

Abstract

An adjustment position of a water output device is provided. A flow volume adjustment component of the water output device has a first position corresponding to a flow volume greater than zero; upon detecting that the flow volume adjustment component reduces the flow volume to that corresponding to the first position, a detection component sends a signal to a control component; and the control component-turns off an electronic waterway switch according to the signal. In this way, when the flow volume is reduced, the electronic waterway switch can be turned off by signal control, and in this case, the flow volume adjusted by the flow volume adjustment component is kept at a particular value, such that the next time water is output by a user using an electronic mode, the failure of water output would not occur.
